C ARBURETlNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 251,416, dated December 2'?, 1881.

Application tiled Jr une 30, 1881.. (No model.)

To all whom it may concern:

Beit known that I, GEORGE W. CRowELL, of Cleveland, in the county of Cuyahoga and State ot' Ohio, have invented a certain new and useful Carbureting Apparatus, ot' which the following is a specification.

The nature and objects of this invention will fully appear from the subjoined description, when considered in connection with the accom- Io panying drawings, in which- Figure 1-is a perspective view. Fig. 2 is a vertical section. Fig. 3 is a side elevation. Fig. 4 is a detached view, showing method of elevating the air-chamber for iniiating it. Fig.

I5 5 is a vertical section otl the air-chamber and air-carburetor.

A is a cylinder or tank for holding water.-

B is an inverted cylinder playing inside ot' cylinder A, andconstitutes an air-chamber.

2o O is an air-carburetor, consisting of a chamber attached to or made in the top of said cylinder B, containing broken and partially-pulverized charcoal and a quantity of gasoline or naphtha.

The air-chamber B is connected to the carbureting-chamber O by a pipe, D.

E is an outlet-pipe in the top of the carburetor, from which the carbureted air is conveyed to burners. The carburetor has a side 3o neck with a cap for supplying the carburetor with gasoline whenever it needs replenishing.

F is a stove or range, the top having holes for cooking-vessels, beneath which are situated burners G G, arranged in connection with the aforesaid carburetor. The stove or range is provided with an oven in the lower portion, and is supplied with burners for heating the same.

The pipe for the burners is connected with 4o the carburetor by a rubber hose, H, which slacks down as the air-chamber descends, and extends when the said chamber is raised for inflation.

Guide-rods I I are attached to the tank A,

for supporting the chamber in its movements while running up and down.

On one side of the chamber B is placed a. rack, J, operated by a crank and pinion, K, for the purpose of raising said chamber when 5o it has run down, for the purpose of reintlation, a check-valve or three-way cock bein g arranged in the pipe D for that purpose.

A branch pipe, L, may be attached to the pipe leading to the burners G, for the purpose of illumination, by providingit with a burner adapted to the purpose. A similar burner may be attached to the top of the carburetor for a similar purpose.

At the rear of the range there may be provided shelves M, for holding cooking utensils 6o when not in use.

The operationof this apparatus is as follows: The carburetor being supplied with a requisite amount of gasoline andthe air-chainber elevated, the communication between said chambers is opened, when the air in the chamber B will find its way into the carburetor by the force of gravity of the said chambers settling down into the water of chamber A. The carbureted air is by this force carried to the 7o burners, and is there consumed. When the chamber B has run clear down it may be elevated again by means of the rack, crank, and pinion, and thereby keeping the burners supplied with carbureted air as long as may be required.

A similar device maybe employed for lighting purposes only by dispensing with the cooking-range and its burners and leading the earbreted air to suitable illuinii'iating lamps dis- 8o posed about a room or building.

rIhe device may be similarly employed for heating rooms by either attaching a heatingdrum in place of the cooking-range or leading the carbureted air through pipes to suitable heating-drums or gas-logs.

This apparatus is therefore practical for all the uses of cooking, lighting, or heating.

The apparatus may be constructed in a variety of forms, either round, square, or oval, 9o and inclosed in neat and tasteful casin g, and ornamented as taste may desire.

Having described my invention, I claim as follows:

The water-tank A, provided with the crank and pinion K and the guide-rods I, in combination with the air-chamber B, provided with rack J, and the carburetor O, located in the upper part thereof, the connecting-pipe D, and eduction gas-pipe E, leading to the burners G, Ioo all constructed and operating as described.
